# PC/SC based smart card backend
|
|
|
|
This crate provides `PcscBackend` and `PcscTransaction`, which are implementations of the
|
|
`CardBackend` and `CardTransactions` traits from the [`card-backend`](https://crates.io/crates/card-backend) crate.
|
|
|
|
This implementation uses the [pcsc](https://crates.io/crates/pcsc) Rust wrapper crate
|
|
to access OpenPGP cards.
|
|
|
|
Mainly intended for use with the [openpgp-card](https://gitlab.com/openpgp-card/openpgp-card) library.
|
|
|
|
## Documentation on PC/SC
|
|
|
|
[PC/SC](https://en.wikipedia.org/wiki/PC/SC) is a standard for interaction with smartcards and readers.
|
|
|
|
The workgroup publishes an [overview]( https://pcscworkgroup.com/specifications/)
|
|
and a [set of documents](https://pcscworkgroup.com/specifications/download/) detailing the standard.
|
|
|
|
The [pcsc-lite](https://pcsclite.apdu.fr/ ) implementation is used on many free software systems
|
|
([API documentation for pcsc-lite](https://pcsclite.apdu.fr/api/group__API.html)).
|
|
|
|
Microsoft [documentation](https://docs.microsoft.com/en-us/windows/win32/api/winscard/)
|
|
about their implementation of PC/SC.
